Sourcetrail is an interactive source explorer that simplifies navigation in existing source code by indexing your code and gathering data about its structure. Sourcetrail then provides a simple interface consisting of three interactive views, each playing a key role in helping you obtain the information you need: - Search: Use the search field to quickly find and select indexed symbols in your source code. The autocompletion box will instantly provide an overview of all matching results throughout your codebase. - Graph: The graph displays the structure of your source code. It focuses on the currently selected symbol and directly shows all incoming and outgoing dependencies to other symbols. - Code: The Code view displays all source locations of the currently selected symbol in a list of code snippets. Clicking on a different source location allows you to change the selection and dig deeper.

Kooder is an open source code search project, offering code, repositories and issues search service for code hosting platforms including Gitee, GitLab and Gitea. There are two modules, gateway and indexer. Gateway is integrated inside gateway under default config.

Livegrep is a tool, partially inspired by Google Code Search, for interactive regex search of ~gigabyte-scale source repositories. To run livegrep, you need to invoke both the codesearch backend index/search process, and the livegrep web interface. To run the sample web interface over livegrep itself, once you have built both codesearch and livegrep. The codesearch binary is responsible for reading source code, maintaining an index, and handling searches. livegrep is stateless and relies only on the connection to codesearch over a TCP connection. By default, codesearch will build an in-memory index over the repositories specified in its configuration file. You can, however, also instruct it to save the index to a file on disk. This has the dual advantages of allowing indexes that are too large to fit in RAM, and of allowing an index file to be reused.

Codase hosts huge amount of open source codes providing a much better coverage, as it covers codes usually hidden inside compressed files and source control repositories, where general search engines fail to find and index. In addition, Codase only indexes and searches high quality codes with every line of code literally validated and compiled by intelligent and powerful source code analysis engine. Codase is a privately held company based in silicon valley, founded by Dr. Huihong Luo and other veterans. We are a group of innovative and passionate professionals with diverse technologies, business background and proven track of records. We are committed to make Codase the world's best search engine for source codes in terms of features, quality, performance and code coverage. If you are a developer, you may find Codase useful, since improving your coding productivity is our goal.

Type any term you want to search for in the search box and press the enter key. Generally best results can be gained by searching for terms that you expect to be close to each other on the same line. Other characters are treated as part of the search itself. This means that a search for something such as i++; is not only a legal search it is likely to return results for most code bases. Any search can be filtered down to a specific source or identified language using the refinement options. Select one or more of each and click the "Apply" button to do this. Filters on the normal interface persist between searches. This allows you to select a specific repository or language and continue searching. To clear applied filters uncheck the filters individually and click on "Filter Selected". You can also click "Clear Filters" button to clear all active filters. The HTML only page filters are cleared between every new search.

Snipplr was designed to solve a simple problem. We had too many random bits of code and HTML scattered all over our computers. We'd hunt and dig around for five minutes looking for the couple lines of code we wrote four projects ago just so we wouldn't have to retype them. We're lazy. We needed a way to keep all of our stuff organized. Snipplr is our solution. Now, all of our code snippets are stored in one place. Best of all, the other guys at work have access to each others' code library. With Snipplr you can keep all of your frequently used code snippets in one place that's accessible from any computer. You can share your code with other visitors and use what they post, too.

Hound is an extremely fast source code search engine. The core is based on this article (and code) from Russ Cox: Regular expression matching with a trigram index. Hound itself is a static React frontend that talks to a Go backend. The backend keeps an up-to-date index for each repository and answers searches through a minimal API. Currently Hound is only tested on MacOS and CentOS, but it should work on any *nix system. Hound on Windows is not supported but we've heard it compiles and runs just fine (although it helps to to exclude your data folder from Windows Search Indexer).

It understands various program file formats and history from many Source Code Management systems. In other words it lets you grok (profoundly understand) source code and is developed in the open, hence the name OpenGrok. It is written in Java. Search for full text, definitions, symbols, path and revision history. Show the matching lines in search results. Online cross-reference with syntax highlighting, highly customizable look and feel using CSS stylesheets. Plugins can be written for new programing language or revision control systems.

Compare project statistics, including activity, codebase, contributors, and more in either a graphical or side-by-side view. Compare languages based on commits, contributors, lines of code changes, and the total number of new projects. Compare types of repositories based on how many of that type are registered with Open Hub. View statistics per language, including most experienced contributors, recent contributors, total lines of code analyzed, total lines of comments, and more.

SymbolHound is a search engine that doesn't ignore special characters. This means you can easily search for symbols like &, %, and π. We hope SymbolHound will help programmers find information about their chosen languages and frameworks more easily. SymbolHound is primarily a programming search engine. Searching for symbols is just not that useful for the average Internet user. Google could probably very easily do this, but it wouldn't make their search engine any better for the vast majority of their user base; in fact, it might make it worse. But for the small percentage of people who find themselves needing to search for special characters, Google is not useful. However, SymbolHound is a symbol search engine and is perfect for that query.
